“When we all join in, I feel like I belong. Let’s play!” Play is the essential activity of childhood. When children engage in healthy play, they develop motor skills, express themselves through music and art, grow cognitively, and create imaginative worlds. This simple, expressive board book vividly shares with toddlers and preschoolers the pleasures and discoveries of play as it explores playing independently, observing others, playing side by side, sharing, taking turns, and cooperating. Includes downloadable bonus activities.
